1. Observe the position and range of empty mines: When attacking enemy bases, first observe the position and range of enemy empty mines, so as to arrange the flight route of balloon pilots. You can send some scouts or flying dragons to investigate and get more information before the attack.

2. Lure the air defense mine to attack: When the balloon pilot approaches the air defense mine, some measures should be taken to lure the air defense mine to attack, so as to prevent the balloon pilot from being hurt. You can use some cheap ground units, such as skeleton soldiers and goblins, to attract the attack of air-raid mines.

3. Pay attention to the number and speed of balloon soldiers: When using balloon soldiers to cheat and search for empty mines, you need to pay attention to the number and speed of balloon soldiers. If the number of balloon soldiers is too small, it may not be possible to lure air mines to attack; If the balloon soldier is too fast, it may be beyond the attack range of the air mine. Therefore, it is necessary to arrange the number and speed of balloon soldiers according to the actual situation.

4. Cooperate with other units' attacks: While using balloon soldiers to cheat and search for empty mines, they also need to cooperate with other units' attacks in order to attack enemy bases from other directions. Some ground units, such as giants, pickups and barbarians, can be used to disperse the enemy's defense, thus increasing the survival rate and attack effect of balloon soldiers.
